To L7/. whom, it muy concern:

. Be it known that l; KARL Burschen, a subject of the King of Prussia, German E1nperor, and a resident of strasse, of Bielefeld, in the Province phalia, German Empire, have invented ceruseful Improvements in Drying Apparatus, of which the following is an exact specification.

M invention relates to drying apparatus for rying articles of different manner containing liquids easily evaporating--as alcohol, ether, water, and the like-in which a new i-ndustrial effect is obtained by the particular leading of the drying-air and utilizing of the heat contained therein. y

ln order to make my invention more clear, l refer to the accompanying drawing, in Which-# Figure 1 is a side elevation ofthe new apparatus. Fig. 2 is a longitudinal section on ine A B of Fi 5. Fig. 3 is a cross-section on line C B ofgFig. 2. Fig. 4 is a horizontal section on line E F of Fig. 2, in which single parts of the vapparatus are moved. a plan view o my improved drying appa4 ratas.

In the drawing, a designates the electromotor for actuating the Yair-cornv ressor b, connected with the electrolnotor by means of a belt.

c d are fans or ventilatorsl operated by the air-motor e4 and driven .by the latter by means of belts f. The air coinpressed'in the air-compressor is conveyed to the air-motor in the manner as hereinafter described.

Thedrying apparatus proper consists of a case g, which may be altered as desired, according to' the special circumstances `'under which the apparatus shall work. it iis e er t,- tbe primary heatingchamber h, and the secondary heatingchambers h', lying at both 'sides of the primary heating-chamber It. 'ln the primary heating-chamber 7L a primary heating system,

consisting of a plurality of heating-tubes t, is

situated and connected with the forcing-tube of the air-compressor by means o a tube m. Furthermore, the heating-tubes i are -iointed to the air-motor e Vby a tube m', the latter' being in comniunication with the receptacle or any suitable tube arbthe purpose of which hereinafter described. i

Specification of Letters Patent.

The secondary heating-chambers h z/ contain heating-tubes i t, being in connection with the drying-room t. by means of tubes 1', as to be seen in fig. 2. At their other ends the tubes i eomi'nunicatc with the suckingoil' tubes n n of the compressor byv nieans'o tubes n n. At the upper emV ofthe apparatus partition-chambers o c are provider having perforated bottoms o The secondary heating-chambers h 7i. are separated from the drying-chamber t by .means of a perforated wall o-. The secondary heatingchambers i and the partition-chambers o are in communication witv the fans b, arrange sideward from theV ease g. The dryingchamber tis opened at both sides.

The foregoing-described drying apparatus l is operated in the" following manner: he -articles'to be dried are introduced into the drying-chamber t at one side and are passed 'through it in a suitable manner. The fans d, driven'by the air-motor e, suck .at both ends of the open drying-chambert JL in the direction upward to the partitionchambers o, from which the air can enter ing-chamber t. is conveyed from fan d, through the the drying-chamber it. At least the air cornes in contact .with the heatingtubes t', arranged in 'ithe primary heatingchanibers h. n its way through the a paratus as before described by the heated) i the liquids contained in the material to be dried are evaporated. In the midst of the apparatus this au' ilows through'the tubes 1 ln that way the dryingair heating-chambers, aroun and through into the heating-tubes i', arranged in the secondary heating-chambers h', from which the air is sucked olf .by the compressor an conveyed to it by means of the, tubes 'a' .ai n a. Inl the compressor the air is compressed and thereby heated and passes then through the tube gm into the heating-tubes fi, arranged inthe riniary heating-chambers h. `From there t de compressed airis conveyed-,by means .of the tube m., motor e, frein whiehvthe fansd aredriven. in consequence of its expansion the air bel cornes cooler.,jso that the alcohol or thelile Ivapors contained in the air condensed, and after.. being conveyed into the tube m`l Q, the alcohol or the like vapors are collected olf the air l and force the air from the heating-chambers p through the'perforated walls o into the dryn one fan d to the followm IOO to the airapparatus, so that nally'the, mechanical teni before being conveyed te zio 2 eezeee therein in e liquid state, while the air dlseherges into the atmosphere. y

Aocording to my invention. I also obtain that the 'Same men-ns serving for driving the i air-,motor 4is employed for heating the drying l Having thusjuliy described the lntture ol g my invention, what I desire to secure by Letl ters Peten t of the United States is- A drying apparatus comprising in oo'nlhination e drying-chamber, prinmry heating tubes, secondary' .heating-tubes inoonnnuniontion with seid drying-chamber, :i prim :try heating-chamber and secondary heatingehambers, fans in Communication with snid Secondary heatin0-elmmbers, n` compressor in connection Witch said secondary hentingtubes, and supplying said primary heatingt'ubes n ith eompreiesedend therefore heated oir, en air-meter in eomnngnieation vsith the q 'primary heatingtubes, and n inotor'ior netufttin saidon res's'or., `snbstentifilly es described. andfor t 1e 'punpose set forth.
